Abstract
In this paper, an analysis of fatigue crack growth (FCG) behavior from a statistical point of
view has been carried out. Fatigue crack growth tests were conducted on sixteen pre-cracked compact
tension (CT) specimens of the pressure vessel (SPV50) steel in controlled identical load and
environmental conditions. The assessment of the statistical distribution of fatigue crack growth
experimental data obtained from SPV50 steel was studied and also the correlation of the parameter C
and m in the Paris-Erdogan law was discussed. The probability distribution function of FCG life and
FCG rate seems to follow the 3-parameter Weibull.
